# THE BUILD TOOL IS NAMED HERE AND NOWHERE ELSE.
# This workflow used to install it through `.xlings.json', a workspace pin that
# `actions/checkout' places in the working directory before anything else runs.
# Two consequences followed and neither was visible in a passing log:
#   * every `mcpp' invocation in this repository resolved to the pinned version
#     rather than to the one the job had installed, because that pin is read
#     from the current directory;
#   * the pin named 0.0.13, from 2026-05. The index no longer serves the
#     toolchain packages a build tool of that age asks for, so `mcpp build'
#     ended at `package 'xim:glibc@>=2.39' not found' before compiling a line.
# The pin file is removed. The version is an environment variable, so the two
# places that need it, the install and the cache, cannot drift apart again.

  pull_request:
  # A CANARY, BECAUSE THIS ROTTED WHERE NOTHING WOULD LOOK.
  # The breakage above occurred between 2026-07-11 and 2026-08-29 and nothing
  # reported it: master received no pushes in that window, so the first run to
  # meet it was a contributor's pull request, whose author had no way to
  # distinguish a broken environment from a broken change.

  # ── The same sources, on a different kernel ABI ──────────────────────────────
  # WHY THIS IS A SEPARATE JOB AND NOT A STEP. It resolves a different toolchain
  # (llvm rather than gcc) and a different everything below the program — musl
  # ported onto openkal, libc++ configured for that musl, and openkal-linux
  # beneath both. Sharing a job would mean sharing a cache key between two
  # stacks that have nothing in common but the source tree.
  # WHAT IT CATCHES THAT THE JOB ABOVE CANNOT. `Socket::write` sends with
  # MSG_NOSIGNAL and `connect_addrinfo` sets SO_NOSIGPIPE, and which of those
  # exists is decided by the C library rather than by the operating system —
  # openkal-musl defines the first and not the second. A `#ifdef` that is wrong
  # about that compiles cleanly here and fails there, which is exactly how
  # 5e7d66f reached master.
